Unity 4.x Game Development by Example Beginner's Guide

Time for action – building the card-flipping function

The game will let the player flip over two cards. Then, it will pause for a brief moment and flip the cards back over. We'll worry about detecting matches for our grand finale in just a moment.

1. Add the following code to your FlipCardFaceUp function:

      function FlipCardFaceUp(card:Card)
      {
        card.isFaceUp = true;
        aCardsFlipped.Add(card);
      
        if(aCardsFlipped.Count == 2)
        {
          playerCanClick = false;
               
          yield WaitForSeconds(1);
               
          aCardsFlipped[0].isFaceUp = false;
          aCardsFlipped[1].isFaceUp = false;
      
          aCardsFlipped = new List.<Card>();
            
          playerCanClick = true;
         }
      }

2. Then, make a small change to one line in the BuildGrid function:

      if(GUILayout.Button(Resources.Load(img),
        GUILayout.Width(cardW)))
      {
    if(playerCanClick) ...
